Kot­te­lat 1991

First descrip­tion: Notes on the tax­on­omy and dis­tri­b­u­tion of some West­ern Indone­sian fresh­wa­ter fishes, with diag­noses of a new genus and six new species (Pisces: Cyprinidae, Belon­ti­idae, and Chaud­huri­idae). Ichthy­olog­i­cal Explo­ration of Fresh­wa­ters, 2: 273287.

Char­ac­ter­is­tics: Over­all length max. 4.5 cm, with an anal fin fil­a­ment, of up to 5 cm. Fin for­mula: Dor­sal: XII-​XIV, 78, total 1922, Anal: XI-​XIV, 1012, total 2224. The ♂ is usu­ally big­ger than the ♀, and has a much longer extended dor­sal fin.

Also, its cau­dal fin is larger and has a sig­nif­i­cantly longer fil­a­ment (up to nearly 1.5 cm). The ven­tral fins of the ♂ have longer fil­a­ments than those of the ♀ and, par­tic­u­larly in older ani­mals, they are often not straight, but formed in an arc. Both part­ners have spot­ted unpaired fins and on the sides of the body, 03 (often 2) con­sec­u­tive thick black spots are shown, which is oth­er­wise found only in P.pahuensis. Some males have sev­eral (up to 15) small red dots around these black spots. The body col­oration varies from light beige to bronze or even bur­gundy. Such a red­dish, pre­vi­ously unde­scribed form with the local­ity name spec. Seruyan seems to be a local vari­ant of this species.

Sim­i­lar species: Because of the struc­ture and colour char­ac­ter­is­tics, the risk of con­fu­sion is low for both sexes (long, speck­led unpaired fins, etc.). P. pahuen­sis has a round cau­dal fin with­out a fil­a­ment and has no zone show­ing red dots on the body sides.

Occur­rence /​Dis­tri­b­u­tion:Linke found the species in Kali­man­tan Ten­gah, 2km north of Suka­mara and 4km south of Pudukali. It occurs near Pan­gal­abuun as well. P. Linkei some­times lives together (syn­topi­cally) with P. opal­lios.

Threat: Since the species inhab­its mainly the south­ern low­lands of Kali­man­tan Ten­gah, it is highly endan­gered despite its wide dis­tri­b­u­tion. The area of occur­rence does not have nat­ural veg­e­ta­tion any­more and is drained and used for agri­cul­tural purposes.

Dis­cov­ery /​First import: The species was found in 1990 by Horst Linke and Nor­bert Neuge­bauer. It was brought to Europe a year later and then named after its dis­cov­erer by Kottelat.

Trade:Today the species is traded occa­sion­ally, as the form ‘spec. Seruyan’.

Care /​Breed­ing:Like other licorice gouramis, but linkeiis known to be robust and less sen­si­tive. There­fore, this beau­ti­ful species is bet­ter suited than oth­ers for own­ers and breed­ers who have lit­tle expe­ri­ence with this group of fish. Some­times a very large bub­ble nest is built. The clutch can be large for big ani­mals (up to 100 or more eggs).

Behav­iour /​Par­tic­u­lar­i­ties:head-​down-​courtship. P. linkei is a highly-​recommended, attrac­tive species.
